cinewhoop drone propeller 2.5 in, 5 blades
Model designed and computed with the Heliciel software. Design point: 23,273 rpm in hover, 50 % throttle on a T-HOBBY Cine25 motor on 4S with a GF D63-3 propeller.
The pack contains the complete propeller as a full-definition STL with root fillet, STEP surfaces (complete propeller and one blade), the Heliciel .hlc project and the computation records. It also contains the same propeller turning the other way (STL and STEP).

This model was designed and computed with the Heliciel software. For a custom propeller there are two ways: the Heliciel software (Windows: computation, 3D view, STL and STEP exports), and the Heliciel MCP connector, which lets your AI assistant — ChatGPT, Claude, Le Chat and any MCP client — compute a real propeller, with a free 1-day discovery pass.
